AFuncDomain Function Domains is a powerful learning aid to help students find the domains of simple rational functions and radical functions.

Interactive Coaching Calculators and Guides combine to speed the learning process.

The Coaching Calculator covers rational functions such as :

f(x) = (3x + 6)/9
f(x) = (x² - 4)/(3x + 6)
f(x) = (x² - 9)/(2x² + 4x - 6)

and radical functions such as :

f(x) = √(2x + 6)
f(x) = √((x² - 5x + 6)

Domains are given in set-builder and interval notation.

The Guide also looks at radical functions such as :

f(x) = -2/√(x - 3)
f(x) = (2x + 3)/(x - √(x + 2))

It's ideal for students as the menu design reinforces each problem solving step.

Examples highlight and simplify algebra that students find hard.
